摘要： A three-dimensional ultrasonic diagnostic apparatus has a cross-sectional image generating unit, a region-of-interest setting unit, a three-dimensional image generating unit and a display unit. The cross-sectional image generating unit generates a cross-sectional image corresponding to a desired cross-sectional plane by performing a two-dimensionally scan on the cross-sectional plane within a three-dimensional scannable region. The region-of-interest setting unit sets a second region of interest for a three dimensional image within a three-dimensional region based upon a first region of interest in the cross-sectional image. The three-dimensional image generating unit performs a three-dimensionally scan on the three-dimensional region including the second region of interest, sets a view point based upon the second region of interest, and generates the three dimensional image, including the second region of interest, in a line of sight from the view point. The display unit displays the three-dimensional image.

摘要： There is provided an ultrasonic wave diagnosis instrument. The ultrasonic wave Doppler diagnosis instrument transmits an ultrasonic continuous wave in a range direction and receives a reflective wave of the ultrasonic continuous wave. The ultrasonic wave Doppler diagnosis instrument includes: a modulation unit that subjects the ultrasonic continuous wave to frequency modulation such that a phase is varied in accordance with the distance of the range direction; a demodulation unit that demodulates the reflective wave for each range of the range direction while interlocking with the frequency modulation, and generates a reception signal in the range in a separated state; and a presentation unit that presents information by using a signal of a Doppler component based on the reception signal.

摘要： A Doppler sensitivity measuring unit measures the Doppler sensitivity of Doppler spectrum data obtained by ultrasonic wave transmission/reception with respect to a predetermined region of an object to be examined. A spectrum shape model generating unit generates a spectrum shape model on the basis of a window function used when the above Doppler spectrum data is generated. A threshold setting unit sets a threshold range in which trace waveform data displaces by a predetermined amount in the frequency axis direction on the basis of the spectrum shape model and the Doppler sensitivity, and sets a predetermined number of thresholds at almost equal intervals in the threshold range. A trace data generating unit selects a threshold for the acquisition of desired trace waveform data by generating trace waveform data while sequentially updating the plurality of set thresholds.

摘要： An ultrasound probe and ultrasonic diagnosis apparatus that can maintain surface temperature of an ultrasound probe within a safe range, without reduction in performance. The ultrasound probe includes a casing, a transducer, an electronic circuit, and a heat-transfer construction. Elements of the transducer are aligned at one end of the casing and send out ultrasound waves in accordance with their respective delay times. The electronic circuit, disposed in the casing, includes a delay circuit setting delay times and pulsers for generating pulses in accordance with the delay times, the pulses being sent to the transducer. While the electronic circuit is being energized, the heat-transfer construction disposes a member having a low heat conductivity at least either between the electronic circuit and the casing or between the electronic circuit and the transducer. Thereby, heat from the electronic circuit is conducted to the other end of the casing.

摘要： To provide an ultrasound diagnosis apparatus capable of appropriately assigning a transmission delay time of a group to a transducer without complicated wires. The ultrasound diagnosis apparatus of the embodiment comprises a plurality of transducers, a timing pulse generator, a switch part, and a switch controller. Ultrasound waves are transmitted to the transducers. The timing pulse generator has output terminals for outputting timing pulses based on a delay time to a channel corresponding to each of the transducers, in which a plurality of output terminals are divided into groups and each group has the output terminals of a specific number greater than two. The timing pulse generator then generates the transmission delay time within a predetermined time range for the each group. The switch part selectively connects the channels with the output terminals. The switch controller divides the plurality of channels into channel regions of the same number as the specific number, and controls the switch part so as to correspond between the groups and the regions by connecting the channels and the output terminals.
